Problem with Phoenix tracks

Hi all. I don't know if it happened to someone else but I have a problem with the 1989 and 1991 Phoenix tracks. Almost all cars drop out by accident. Any solution?

I’ve had the same issue. Unsure of fix as I filed back all the pertinent MD numbers(?).

Get the damage coefficient down to 0 with GP4Tweaker!

Try reducing AI errors in the track's magic data, that should do it.

When you say "by accident" do you mean they crash out? Or retire with reliability problems? Or run out of fuel?

Yes, I meant that cars crash.

Hi. If you mean to do it from TSM, it hasn't worked for me either.

I'm a total dick. How many people can say that?

Mostly at the end of the back straight, right? I've seen this problem myself before...

I believe GP4 has a bug (what, another one?! ) where the AI cars seem to assume the track width stays constant from the start of the corner. This causes a problem when you turn sharply from a wide track to a narrow track, exactly like Turn 9 at Phoenix (Washington St into 3rd Avenue).

When being overtaken, an AI car will stay on the outside line, rather than the racing line / CC-line. They try to drive the same wide line all the way around the corner, but when the track narrows they hit the wall because they don't expect it there.

There is no solution to this that I could find, only a "hack", which is to edit the .dat file to widen the track on the outside of the corner. Graphically the track looks the same and there is no unfair advantage (the AI won't use the extra width normally because the CC-line remains the same).

Unfortunately the problem is especially pronounced at Erik van Leeuwen's version of Phoenix (which I assume is what you're using) because the track .dat file has a slight glitch at that corner anyway and also the Magic Data is not the best (sorry to the authors for being critical, it is a great track otherwise).

Here's how I hacked fixed it:

Hi bro, thanks to you and everyone else for your comments and input. Yesterday I made magic datas modifications and at least doing the race simulation with the accelerated time no longer crashing so many cars, which allows a satisfactory race. I have not yet tested the track in a real race and this observation of yours has made me doubt. Would you mind sharing the file you corrected with me? Thanks in advance.

Sure, try this: [www.dropbox.com]

Mind sharing your Magic Data fixes too? What values affected the fix?

Hi Tom. I took the track from a 1989 mod that I downloaded from 4shared (can't remember the author), I used GP4Builder to tweak it for AI errors and mechanical failure probabilities. All of these values ​​were zero (0). I removed the original magic data and replaced it with one I took from the 1982 trackpack that Soutsen sent me. I also modified the lap threshold for pit stops. These modifications have been tested in fast-time simulations and typically finish 12-15 cars. Before it was only one, the winner. The mods I have tested have been kedy and GP4Central, with 22 cars competing. I've made magic data modifications to other tracks as well, in case you're interested.

P.S.: In the link you sent me there is no file. Says he was eliminated.

Hi friend. The mod I am talking about I downloaded from 4shared being redirected to gp4forever. From that mod I took the track in question.

Hmm ok I assumed the 1991 version. Sorry for the bad link, try this: [www.dropbox.com]

I'll take a look at the 1989 version.

OK I got a bit carried away with fixing up the 1991 version of Phoenix by Erik van Leeuwen, cleberpister & plodekk. Here's an updated version containing:

- Improved .dat file in several places
- New CC-line
- New Magic Data
- New Loading Screen (Hi-res)
- New Settings .ini file

Hi Tom!

Could you (or anyone who have it), the 1991 track updated? The link is no more...
